Just wondering what those of you who have installed a nav. unit used as a vehicle speed sensor connection. I'm thinking of using the signal wire to the speedometer. Unit is a Pioneer AVIC D-1

I was unaware my gesture as subtle as mine was would illicit a narcissistic rant based on a question. However I appreciate you taking time to respond and I will look into your advice.

Suggest you not take your self too serioulsy in the future.

Applies to all 850s?

now this is really from memory, my 94 didnt have it iirc. i do remember going to the abs sensor up front. but my 95 glt na had it behind the radio. Dont know if i didnt know to look at the radio harness or what.

if the radio harness has a yellow/black and when you use a radio harness and on the oposite side there is nothing connected...thats is the vss wire then. i honestly cant be for sure, since its really been a long time since i seen behind a 96 and older 850

Thanks for the tip. I pulled up some '96 schematics and they have VSS going to the radio. I need to check on my 850 because I need to wire up my dead reckoning GPS receiver for the carpc.

Found it. Behind the gauge cluster there is a cover that you can remove (use a utility knife to cut part of the 4 sides). Behind that there will be 2 male blade connectors. These should output a digital signal of 24 pulses per tire revolution (both are the same). Non-invasive and simple way to access the VSS. Specifically intended for accessories that need a vehicle speed signal.
